Case Study

Q/A

Typical SLAs from Cloud Providers

We guarantee 100% Server Uptime

30 Minute Support Response Time Guaranteed (QoS)

Issue of Service credit, in case of breach in SLA

SLA: An explicit statement of expectations and obligations that exist in

a business relationship between two organizations: the service provider and

customer


SLA

We guaranty that our data center network will be available 99.999% of the time*

We guaranty that data center HVAC and power will be functioning 100%*

We guaranty that the load balancing service will be available 99.99% of the time

“Traditional SLAs focus on narrow aspects of infrastructure rather than the

comprehensive application experience. Because businesses run on applications,

new SLAs must be defined at the application level to properly support the business,” - Peter Sevcik, President of
